Application led July 29, 1914. Serial No. 853,839.

To all whom it may concern.'

Be it known that I, HENRY HARDrsrY, a citizen of the United States,residing at Raymond, in the county of Pacific and State of l/Vashington,have invented a new and useful Choker-Hook, of which the following is aspecification.

The invention relates to improvements in logging hooks.

The object of the present invention is to improve the construction oflogging hooks and to provide a simple, practical and eflicient chokerhook of strong and durable construction, adapted to grip a line and holdthe lsame securely around a log, so that it will be impossible for thelog to run through the line or the latter to slip over the end of thelog. Y A further object of the invention is to provide a hook of thischaracter equipped with a line or cable clamping member provided withlogging means adapted to be easily and quickly operated to fasten andunfasten the clamping member and capable of effectually preventing thedevice from accidentally unhooking while logging on extremely rough 1ground.

It is also an object of the invention to pro- .vide a closed choker hookwhich will not ,clog or foul with mud and which will effect y a savingof time and labor and lessen the eX- pense of handling logs.

' With these'and other objects in view the invention `consists in theconstruction and .novel combination of parts hereinafter fullydescribed, illustrated in the accompanying drawing, and pointed out inthe claims appended hereto, it being understood that various changes inthe form, proportion, size and minor details of construction, within thescope ofthe claims, may be resorted to without departing from the spiritor sacriicing any of the advantages of the invention.

In the drawing :-Figure 1 is a'perspec-` 5 is adetail sectional view onthe line 5--5 of Fig. 3. I 4

Like numerals of reference designate corresponding parts in all thefigures of the rawing.

In the accompanying drawing, in which is illustrated the preferredembodiment of the invention, 1 designates a hook designed to beconstructed of tool steel or other suitable material and consisting ofan extended side 0r shank portion 2, a short side or bill 3, and aconnecting bottom portion 4. The sides and bottom portion constitute thebody of the hook, which is comparatively broad to provide a relativelylarge surface for engaging a line or cable (not shown). The extendedside or shank 2 is provided at the Vtop or outer end with an integraleye 5 for Visv curved longitudinally of the hook to receive and conformto the configuration of a line or cable, and it is also curvedtransversely to present a convex inner face 6 to the same. The body ofthe hook is preferably provided at its outer face with eX- teriorlongitudinal grooves 7 to lighten the structure, but these may or maynot be employed. The hook is designed to be constructed of differentsizes to suit different diameters of lines or cables7 and the short sideor bill 3 is reduced at opposite sides of thebody to form an upwardlyprojecting eye 8 for the reception of a pintle 9 which hinges a clampingmember 10 to the side or bill 3 of the hook. The clamping member 10,which is approximately L-shaped, consists of a jaw 11 provided at theinner portion with an upwardly extending lip or flange 12, andbifurcated at the outer portion to form a central recess 13 to straddlethe eye 8 and having spaced eyes 14 located at opposite sides of the eye8 and receiving the terminal portions of the pintle 9, which ispreferably headed at its ends 15.

The clamping member, which swings inwardly and outwardly in thelongitudinal plane of the hook, is adapted to engage and frictionallygrip a cable or line, which is firmly held between the inner or lowerface of the jaw of the clamping member and the inner or upper face ofthe bottom connecting portionfl of the hook. The upwardly eX- tendinglip or flange 12, which is preferably of segmental form, is arrangedsubstantially at right angles to the jaw or engaging portion 11, and hasa fiat inner face to t against the innei face of the extended side orshank of the hook when the clamping member is inits closed position.Thel jaw, which extends across the mouthor entrance of the hook, islocated below the upper or outer end of the short side or bill 3 of thehook, and the said jaw is provided in its upper orouter face with atransverse groove 16, adapted to receive the terminal portion of agravity arm 17 of a key 18, which locks the clamping member in itsclosed-or engaging position.

The key 1S is provided with a stem 19V arranged at right 'angles to thegravity arm and having a laterally projecting `lug 20. The stem, whichis round, is slid'ably mounted=in` a circular opening 21 in the lip or'flange 12, and it is adapted to extend through' an opening 22 in theextended side or" 'shank of the hook. The opening 22 is provided at'thebottom with a reduced eX- tension or recess 23, which forms a passageway'f'or the lug 20 when the latter, through the 4rotary movement'of'the stem, is'brought to the bottom thereof opposite the-recess 23.The lip'or iiange 12f is provided at its inner face' with a recess24,1ocat'ed at the bottom of the round opening 21 and' registering withthe recessl 23 wheny the clamping member is closed, and adapted topermit 'the stemof the key to'be drawn outward a suiiicient distancetoarrange its inner end invsubstantiallyffiush relation with the innerface of the lip or langeto carry the said stem and the lng =clear` ofthe 'extended sideor shank of the hook. W hen the key'is in` thisVposition, the clamping li'ineniberis unlocked and may berswung to-*itsopenposition'. When the "clamping member' is' =c`losed, the stem' of thekey is adapted to l'be moved inwardly" or rearwardly to `carrythe lug2O2through the reduced branchor recess 23 into a rear recessorenlargement 25,'of sufficient sizeto permit theilugto 'be carried4away fromthe recess 23 byA a partialE rotary movement of the stem. yTherecess '25 lis preferably circular and the gravity'arm 17, which extendsfrom thestem'in a direction' approximately diametricallyopposite the lug20,' isadapted, when swung downwardly into the' `exterior groove'lG ofthe jaw ofthe clamping member',rto' maintain the lug 20 out of alinementwith the recess 23. The gravityl arm is adapted to swing' to eithersideto carry the lug 20' away from the-recess 23 to lock-the key inengagement with the extendedy side or shank of *the hook, and theclamping member constitutes a guard for protecting the key, which cannotbecome accidentally unlocked, 'as it is necessary to 'elevate thegravity "arm to a central vertical position and thendrawthe'key'outWardly.V As? the clampinglmember is securelyflocked when thegravity arm is at either side ol1 the hook,

-Q itfis unnecessary to employ aispring rin the lockingmechanism. VVhenthe cable to which the choker hook is connected is placed 'under'tension, there is a strain on 4the `clamp-v vout of theprotectinglgroove of the clamping member when the device is not in use.lllh'at is claimed'is:
